CORN-HUSKING ROLLER/S.

Specification of Letters Patent.

Patented April 27, 1909.'

Application filed December 26, 1908. Serial No. 469,379.

an improved form rif-peripheral surface' adaptedto coact with a corresponding one in an aggressive and efficient manner in the operation of removing the husks from the cars of corn. This object is attained by means of the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a top view of a pair of husking rollers embodying my invention; Fie. 2 is a cross section of'Fig. 1 along the line A-B;

and Fig. 3 is an end view of Fig. 1, illustrating the manner of .mounting the rollers, one of them` being journaled in a laterally, yielding springLpressed sleeve that allows it to ield away from its coacting roller when sub- Jected to undue strain.

The same reference numerals designate similar parts throughout the several views. v1 designates a frame ,memberl having bracket members 2 secured to opposite ends thereof, the brackets being provided with bearing boxes 3 and 4 that are loosely received in openings therein, the box 4 being permitted to move laterally in the opening rovided for it; and 5 designates a lever aving one end (pivotally connected with the bracket at V,6 anl its opposite end contacting with the box 4. A bolt.7passes through the middle portion of the lever and through an ear 8 upon the bracket,and 9 designates ,a spring coiled about the bolt and operative between an adjusting nut 10 and said ear to yieldingly press the lever against the box.

Husking rollers 11 and 12 arejournaled in the boxes 3 and 4, respectively, the roller 11 being placed in a plane above that of itsco-v acting roller 12, as is common in this class of machines, and motion is communicated to the rollers by means of gear members 13. The rollers are provided" .at opposite ends thereof with short concentric portions 14,

for the purpose of producing a steady rolling movement thereof when the concentric portions are in contact with each other. '.l'he body portions of the rollers are designed to engage with the husks in a manner to strip theni from the ears of corn, and for this purpose are given rapid rotative movement in opposite directions t'o their axs, and in' order that they may perform that function in an efficient manner, they are provided withsurfaces having a novel for1n which inco- 6.

active operation will aggressivel grasp the husks and remove them from t e ears, including opposit'ely 'disposed Vsurfaces. l15, having an involute form relative to the axis of rotation and extending .lengthwise ofthe roller substantially parallel with`its body, and intermediate concentric surfaces 16 that are also oppositely disposed and are connected wit the involute portions in the direction of rotation of the rollers by means of short tangentially arranged surfaces 17 connecting with the involute portions at the line having the shortest radius.

18 designates radiallyprojectirrg teeth that are raised above the surface of the involute '80 portions and a're arranged in a series` of groups of three 1n clrcurnferentlal' lines about Ithe axis of the roller, and in a line with its body, with intervening spaces between the groups; and 19 designates teeth raised above the tangentially arranged surfaces, the teeth being opposite the spaces between the grou s lupon the involute surfaces and in' a line su stantially parallel with the body of the roller.

The 'teeth are preferably given a ratchet-like 90` form, with-the radial sides in the direction of rotation of the rollers about their axes, and l are arranged upon separate rollers so that the groups of teeth upon one roller will 'be presented against the spaces between the coacting rollers and in like manner the teeth upon the tangentially arranged portion of the roller will be presented against the spaces between the corresponding rollers.

What I claim asy my mventlon, and desire 10o to secure by Letters Patent, isz

1. A corn husking roller having oppositely disposed involute peri heral surfaces, and a series of groups of ra( iall'y projecting teeth arranged in circumferential lines thereon.

2. A corn husking'roller having opposite'ly disposed involute peripheral surfaces, and intermediate concentric surfaces, said invoeuri'aces having a series of groups of r ally projecting teeth arranged in circun1- imrntial lines thereon.

B. el c 'n husking roller having oppositely sed involute peripl'ierel surfaces, and rrnediate concentric surfaces, said invoeuriaces having a series of groups el' radially projecting teeth arranged in circuinif .":nlial .es thereon, and a series ol' teeth open said concentric surfaces.

l. cern liusliing roller having o} )positely disposed involute peripheral surfaces, intermediate concentric surfaces, said involute surfaces havinga series of groups oi radially projecting teeth arranged in circumferential lines thereon, and a series oi' teeth upon said 4concentric surfaces arranged opposite the 'spaces between said groups of teeth.

A corn husliing roller having oppositely disposed involute peripheral surfaces, and a series of groups of radially projecting teeth thereon, each group of teeth being arranged in circuinierential lines relative to the axis of the roller, anda series ol groups in a line substanti-al',

. corn husliing roller having o p positely f' parallel with the body oi'v the roller.

disposed involute peripheral surfaces, interA mediate comi-,entric surfaces, said involute surfaces having a series oi groups ol" radially projecting teeth thereon, said groups ol' teeth zbeing arranged in circumferential lines relative to the axis oi' the roller, and a series ol' groups in a line substal'itially parallel with the body ol' the roller, and a series oi" teeth upon said concentric surfaces arranged oppo` site the spaces between said groups of teeth and in a line substantially parallel with the body of the roller.

7, A pair of coacting corn husliingroliers having opposing'iinvolute peripheralsilriacesv provided with teeth, and intermediate opposing concentric surfaces.

8. A pair'of coacting corn husking rollers having opposing involute peripheral surfaces provided with teeth, intermediate opposing concentric surfaces, and opposing surfaces arranged tangentially relative to the axis of the rollers.4
